Counting macros is a popular tool for when you decide that you want to lose weight, build muscle, or track your nutrition for diseases like diabetes. Using a calorie calculator, you can find out what percentage of your calories come from which macronutrients—carbohydrates, proteins, and fats—which should give you an idea of how to adjust your diet to accomplish your goals. But does it work?
The short answer is, it can. The longer answer is that it depends on a lot of factors. One of those is food quality and making sure you have accurate information. Luckily, technology has made accurate tracking easier with apps. In this list we'll give you the best macro tracking apps and explain what you'll get from each. As for food quality, we recommend using a healthy meal delivery service if you're too busy to cook. These services also typically give you accurate nutrient information on the recipes.

FAQs About the Best Macro Tracking Apps
Does tracking macros really work?
Yes, tracking your macros can help you accomplish your goals whether it is to lose weight or gain muscle. But like any nutrition plan, eating good quality food and exercising is key.
How do I figure out macros to lose weight?
Everyone's body is different, so the macro split you'll need to lose weight may take some trial and error. First you need to figure out how many calories you currently eat, and if you are gaining weight, plan to consume less. If you are maintaining weight, then switch up your macro split.
For example, if you eat 2,400 calories per day and you get 50% from carbs, 30% from fat, and 20% from protein, you may benefit from decreasing your carbs and increasing your protein percentage.
What should my macros be to lose weight and gain muscle?
Typically, if you want to lose weight and gain muscle you need to target your body's fat stores for energy. To do this you should adjust your macro split to be less carbs and more protein and fats.
The USDA recommends a split range of 45-65% carbs, 10%-35% protein, and 20%-35% fats. To lose weight and gain muscle, try keeping the carbs as low as possible and use the extra percentage in your proteins.
